The premium "no ads" feature does remove visual promos and banner ads from the app. But if you're referring to audio ads you hear in episode recordings, we'd love to remove them for you. However, it's something we have no control over and are injected by the publishers.

If you're still seeing ads and you are sure you're logged in with a valid premium subscription, please contact support via Settings > Help > [Contact us] and send logs so we can investigate this for you.
